Squirrel-Tail Grass Or Wild Barley., L. H. Pammel 2017 Iowa State College

Squirrel-Tail Grass Or Wild Barley., L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

For nearly fifteen years the writer has been familiar with the subject of this paper. It has always appeared to me to be an aggressive weed and hence most undesirable for the farmer. During the last few years I have at various times received the weed from correspondents in this and other states, but during the past season the demands for information about this grass have been more frequent. It would therefore seem a public duty to describe and give an account of the weed so that farmers may better be able to cope with it. Farmers annually lose many ...


Cottonseed Meal To Hogs., C. F. Curtiss 2017 Iowa State College

Cottonseed Meal To Hogs., C. F. Curtiss

Bulletin (Iowa Agricultural Experiment Station)

Cotton-seed meal was quite extensively introduced as a stock food in the northern states last winter by reason of its heavy production in the southern states and the severe drouth prevailing in the corn belt in 1894, and consequent high price of corn and other grain feeds. The introduction of this feed brought the station many inquiries concerning the feeding value of cotton-seed meal and the practicability of adopting it in feeding rations. We have fed it to the extent of six and seven pounds per day to dairy cows and fattening cattle with good results and no apparent injury ...


Best Ferns For The North And Northwest., G. W. Carver 2017 Iowa State College

Best Ferns For The North And Northwest., G. W. Carver

Bulletin (Iowa Agricultural Experiment Station)

Owing to the great beauty and usefulness of the ferns in decorative lines,and the difficulties with which they are grown in the North and Northwest, numerous inquiries have come to us from time to time as to the best varieties. This led us to make some experiments in this direction.

A large number of ferns have been subjected to very rigid tests for several years, and the results have indeed been gratifying, as we have proven beyond doubt that many of the most beautiful ones will thrive and soon make handsome specimens with a little care.


Experimental Crop Notes For 1894., C. F. Curtiss 2017 Iowa State College

Experimental Crop Notes For 1894., C. F. Curtiss

Bulletin (Iowa Agricultural Experiment Station)

Since interest in winter wheat growing has revived in some sections of Iowa considerable merit has been claimed for the press drill over other grain drills and other methods of seeding. The Hoosier Press Drill Co., of Richmond, Ind., furnished the Iowa Experiment Station a drill free of charge, and we deemed it of interest to test its value for sowing winter wheat. Accordingly, on October 2, 1893, a small piece of ground, that had grown a crop of oats and vetches, was plowed to a depth of five inches and disced and harrowed thoroughly, and one-half of the piece ...


Soiling Crops 1894., James Wilson 2017 Iowa State College

Soiling Crops 1894., James Wilson

Bulletin (Iowa Agricultural Experiment Station)

Our station pursued its line of inquiry in feeding soiling crops, through July and August of 1894. No rain fell from the 23d of June until the 10th of August. The pastures were dried up and stock that was not fed by hand suffered more severely than at any time since the prairies of the State were enclosed and animals were confined within. fences. The drouth affected pastures unusually early, continuing all summer, strengthening our conviction that successful animal husbandry in the State requires additions to our cropping system that will furnish plants in their best condition for feeding during ...


The Russian Thistle In Its Natal Home., J. L. Budd 2017 Iowa State College

The Russian Thistle In Its Natal Home., J. L. Budd

Bulletin (Iowa Agricultural Experiment Station)

Prior to the writer’s visit to East Europe in the summer of 1882, attention was directed to the plant we call Russian Thistle by a note in Prof. Henfrey’s well known work, "The Vegetation of Europe, its Condition and Causes,” as follows: “On the steppes east of the Volga one curious thorny plant has attracted the attention of most travelers, the “Wind Witch,” as it is called by the German colonists, or “Leap the field,” as the Russian name may be translated. It forms a large globular mass of light wiry branches interlaced together, and in autumn decays ...


Report Of The Chemist., G. E. Patrick 2017 Iowa State College

Report Of The Chemist., G. E. Patrick

Bulletin (Iowa Agricultural Experiment Station)

At the request of the Director three samples were taken from the Russian Thistle plat on as many different dates, two weeks apart, and submitted to chemical analysis. The samples were taken by cutting within half an inch of the ground; the “heights” reported below are from measurement of the samples after cutting.


Botany Of Russian Thistle., L. H. Pammel 2017 Iowa State College

Botany Of Russian Thistle., L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

The widespread interest manifested in our state and elsewhere in the northwest indicates that the Russian Thistle (Salsola kali, variety traqus), is a miserable and execrable weed, doing much injury to agriculture.

At the request of the Director of the Experiment Station I have devoted a little time to the botany of this weed. Some attention has therefore been given to the study of the weed, its germination, the anatomy of the root, stem, leaf and seed. A study of the anatomy will be of interest, because its structure may best adapt it to growing on high, dry soil. Professor ...

Corn Meal And Grass With Stock Steers., D. A. Kent 2017 Iowa State College

Corn Meal And Grass With Stock Steers., D. A. Kent

Bulletin (Iowa Agricultural Experiment Station)

The object of this experiment is to determine whether it would pay to feed the stock steer while running in pasture. The experiment has been confined to one variety of dry feed (com meal finely ground.)

Fourteen steers were put in the experiment, six two-years-old and eight yearlings. Twelve were Holsteins and two were Short-homs. One Short-hom and six Holsteins constituted each lot. Two fields of seven acres each were provided for pasture. The cattle were turned to pasture on the 22d day of May, 1893. The pasture was seven inches high and consisted chiefly of clover with a good ...


Specific Gravity And Weight Of Wheat Seeds., L. H. Pammel, F. C. Stewart 2017 Iowa State College

Specific Gravity And Weight Of Wheat Seeds., L. H. Pammel, F. C. Stewart

Bulletin (Iowa Agricultural Experiment Station)

Little work has been done in this country on the specific weights of our seeds. Such studies have been made of European wheats by Harz1, Nobbe2, Koemicke and Werner3, and others.

Our work was started primarily to determine the influence latitude and climate had on the germination of seeds, but as there appeared to be so much difference in the size of wheat, it occurred to us that a study of the specific gravity and number of seeds per pound and bushel might be of interest.


Sugar Beets In Iowa, 1893., G. E. Patrick, O. H. Pagelsen 2017 Iowa State College

Sugar Beets In Iowa, 1893., G. E. Patrick, O. H. Pagelsen

Bulletin (Iowa Agricultural Experiment Station)

Co-operative work with farmers in the study of sugar beet culture was continued during the past year, and on the whole with very encouraging results.

Forty-one farmers entered into the work, taking seed in the spring, under agreement to cultivate according to directions and send in samples of the crop for analysis, but several of them failed to secure a crop which they considered worthy of chemical investigation and therefore sent no sample. Several persons, however, who obtained their seed elsewhere requested that their beets be analyzed at the station; which requests being granted, the total number of those sennding ...


Results Of Crossing Cucurbits, L. H. Pammel 2017 Iowa State College

Results Of Crossing Cucurbits, L. H. Pammel

Bulletin (Iowa Agricultural Experiment Station)

The writer has on several occasions expressed his views on the subject, crossing of cucurbits. The views expressed have met with some opposition among professional gardeners, horticulturists and many farmers who cling tenaciously to the old notion, that pumpkins and melons will “mix.” So far as I know the results of our work at the station are in harmony with those made by other investigators in both Europe and America.

In a former bulletin of this station the results of our work for 1892 were given. In this bulletin will also be found references to some of the literature on ...


A Study Of Ripening Corn, C. F. Curtiss, G. E. Patrick 2017 Iowa State College

A Study Of Ripening Corn, C. F. Curtiss, G. E. Patrick

Bulletin (Iowa Agricultural Experiment Station)

In the fall of 1892 a line of investigation was undertaken by the writer with a view to determining some of the successive changes that take place in a crop of com in the process of ripening, and also to ascertain the character, composition and quantity of product, and an indication of its feeding value, when harvested in different stages of growth. To this end five plots of one-fifth of an acre each of good well grown field com were put in shock at intervals of a week, commencing on September 17, and ending October 18, and in addition a ...


Soiling, James Wilson 2017 Iowa State College

Soiling, James Wilson

Bulletin (Iowa Agricultural Experiment Station)

During the summer of 1893 this station continued inquiry into soiling crops begun in 1891. The long continued drouth beginning in July and continuing into October, resulting in bare pastures and great loss to owners of all domestic animals, makes necessary thorough inquiry into all plants suitable to our soil and climate that mature during the months when experience shows us something must be prepared to supplement the pasture.

Much can be done by preparing well seeded acres, or ample area, to keep stock over short dry periods, but it is evident that such long drouths as we had during ...


Genetic Analysis Of Anthocyanin Content In Purple Waxy Corn (Zea Mays L. Var. Ceratina Kulesh) Kernel And Cob, B. Harakotr, B. Suriharn, K. Lertrat, M. P. Scott 2017 Thammasat University

Genetic Analysis Of Anthocyanin Content In Purple Waxy Corn (Zea Mays L. Var. Ceratina Kulesh) Kernel And Cob, B. Harakotr, B. Suriharn, K. Lertrat, M. P. Scott

M. Paul Scott

Anthocyanins of pigmented corn become a topic of increasing interest recently due to consumer awareness of their various health benefits. A better understanding on the gene effects to anthocyanin is an important for high antioxidants breeding programs. The objective of the present study was to determine gene effect controlling of anthocyanin content in purple waxy corn kernel and cob by generation mean analysis. For the cross of KND 10-4P (P1) × BW (P2), F2, and backcross generations were developed. All generations were planted in the randomized complete block design (RCB) with 3 replications at the Khon Kaen University, Thailand. Genetic analysis ...


Phenotypic Characterization Of Inbred Lines And Their O2 Conversions, M. P. Scott 2017 United States Department of Agriculture

Phenotypic Characterization Of Inbred Lines And Their O2 Conversions, M. P. Scott

M. Paul Scott

Peter Loesh was a plant breeder at Iowa State University from 1971 to 1980. During this time, he worked extensively with the o2 mutation in an effort to improve the nutritional quality of maize. Unfortunately, he passed away suddenly, and this work was not brought to a conclusion. Some of his effort was devoted to developing o2 back-cross conversions of public domain inbred lines. Because Dr. Loesh’s field books have been lost, the extent of recovery of the recurrent parent phenotype is not known.


Tissue-Print Immunodetection Of Transgene Products In Endosperm For High-Throughput Screening Of Seeds, M. Paul Scott 2017 United States Department of Agriculture

Tissue-Print Immunodetection Of Transgene Products In Endosperm For High-Throughput Screening Of Seeds, M. Paul Scott

M. Paul Scott

This method allows high-throughput qualitative screening to identify seeds containing a transgene product in endosperm tissue. It is particularly useful for determining genetic segregation ratios or identifying seeds to be advanced in a breeding program. Tissue printing is used to avoid time-consuming extraction steps. Antibody-based detection of the transgene product makes this method suitable to any transgene product for which a specific antibody is available. It is possible to screen thousands of seeds per week using this method.


Comparison Of Tungsten Carbide And Stainless Steel Ball Bearings For Grinding Single Maize Kernels In A Reciprocating Grinder, Jay Hoch, Adrienne Moran Lauter, M. Paul Scott 2017 Iowa State University

Comparison Of Tungsten Carbide And Stainless Steel Ball Bearings For Grinding Single Maize Kernels In A Reciprocating Grinder, Jay Hoch, Adrienne Moran Lauter, M. Paul Scott

M. Paul Scott

When grinding many corn kernels at once, there are several different options to choose from, but single kernel grinding is limited to few options with relatively low throughput. An attractive alternative is a reciprocating grinder with 3/8” grinding balls and a 4ml polycarbonate vial set. This format allows grinding of 24 samples simultaneously, which is a significant improvement to grinding throughput. A reciprocating grinder like the Talboys HT Homogenizer (Troemner, Thorofare, NJ), operates by violently shaking the 4ml polycarbonate vials containing a bearing and a single kernel. In our experience, stainless steel ball bearings do not lead to a ...


Allelism Testing Of Maize Coop Stock Center Lines Containing Unknown Brown Midrib Alleles, L. J. Haney, S. Hake, M. P. Scott 2017 United States Department of Agriculture

Allelism Testing Of Maize Coop Stock Center Lines Containing Unknown Brown Midrib Alleles, L. J. Haney, S. Hake, M. P. Scott

M. Paul Scott

This report summarizes the allele testing of brown midrib stocks characterized by phenotype only in the Maize Coop Stock Center collection. Maize seeds obtained from the Maize Coop Stock Center were planted in the summer nursery of 2006 and 2007 at the Agronomy Farms of Iowa State University (Boone County, IA). Each of the lines containing a homozygous recessive unknown brown midrib allele was crossed to a series of lines, each containing a different homozygous recessive known brown midrib allele. The F1 plants were screened for reddishbrown pigmentation in the leaf midrib at the V8 stage of growth. Presence of ...
